I have a mint black Zeiss Biogon ZM 28mm f/2.8, that I'm looking to trade for a 35mm Biogon f/2, 50mm f/2 Planar, or a 50mm M-Hexanon.

Also, I'm interested if anyone is willing to trade their 50mm Summilux-M pre-ASPH.

We'll figure out if any cash is necessary to even the trade.

Looking for black lenses only.

I can also sell sell the lens if anyone is interested, price $600.
